PRODUCT OVERVIEW

When the relative humidity in the power distribution box exceeds 65%, EFR012 will control the heater heating, in order to reduce the moisture condensation and effectively prevent corrosion. Compared with mechanical thermostat, EFR012 with low hysteresis, making it’s switching point and setting accuracy more precise.
